How can a Raspberry Pi be powered from a lab power supply via USB?
I have a lab power supply that can easily output 5 V/4 A and I would like
to use it to power a Raspberry Pi (version 3B and 3B+).
In theory one could attach the power directly to the +5v pin in the header, but that means bypassing the over-current and over-voltage protection provided by the USB circuitry. Thus I would like to use the USB port.
Is it enough to wire the positive and negative rails of the lab power supply to the +/- pins of a male micro USB connector?
Should the data pins be left unconnected/floating?

That should work. The data pins are not connected at the Pi end of the microUSB socket, the socket is purely for power.
